Example of function using bitwise operations for converting hexadecimal color (usually given as 6 hexadecimal digit string, into separated RGB integers) <?php function hex2rgb($hex){ $dec = hexdec($hexcolor); // $hex string to decimal value $r = $dec & hexdec('FF0000'); //Mask for red $g = $dec & hexdec('00FF00'); //Mask for green $b = $dec & hexdec('0000FF'); //Mask for blue return array($r>>16, $g>>8, $b); // Shift full right each color from its original position } ?> Example of use <?php $rgb = hex2rgb('112233'); echo "red: ".$rgb[0]."\n"; echo "green: ".$rgb[1]."\n"; echo "blue: ".$rgb[2]."\n"; ?> Would produce: red: 17 green: 34 blue: 51 Since: dechex(17) = '#11' dechex(34) = '#22' dechex(51) = '#33' ---- Server IP: 72.52.91.14 Probable Submitter: 2001:7e8:c600:5501:4578:33be:1acb:8b4b ---- Manual Page -- http://php.net/manual/en/language.operators.bitwise.php Edit -- https://master.php.net/note/edit/118164 Del: integrated -- https://master.php.net/note/delete/118164/integrated Del: useless -- https://master.php.net/note/delete/118164/useless Del: bad code -- https://master.php.net/note/delete/118164/bad+code Del: spam -- https://master.php.net/note/delete/118164/spam Del: non-english -- https://master.php.net/note/delete/118164/non-english Del: in docs -- https://master.php.net/note/delete/118164/in+docs Del: other reasons-- https://master.php.net/note/delete/118164 Reject -- https://master.php.net/note/reject/118164 Search -- https://master.php.net/manage/user-notes.php
